Over the years we’ve covered a lot of registry hacks, and while most people can handle the step-by-step instructions for how to make a registry change, or double-click a .reg file to insert it into the registry, you will be much better served having a solid knowledge of what the registry is and how it works.

One thing missed here, though it is generally more useful for Enterprise admins than home users, is the ability to connect to the Registry of another system across the network. It's especially handy if, for whatever reason, RDP to that system is unavailable.
